300 mtr shoot with my H&R M1 Garand.

[Ex Crab]

That's breathing...

Normally yes, but I always hold my breath, then close my eyes count to three and open my eyes. If i'm still on aim then all is well. Mostly my aim does not wonder. So I must have screwed things up by some other method. However I reckon that 1.5 MOA for a rifle of that era is above average performance. I thing that the very best might just reach 1 MOA, which if I can sort out my act might be achievable. Have to wait and see.
